New patch, supersedes the last one. The change is implemented as non–ABI-
breaking, with the introduction of av_get_frame_filename**3**, but it
raises the issue of the old implementations kicking around, which should
probably be deprecated (with the changes announced in the API changelog).
I decided this is a necessary change to support the frame_pts option
properly since the old code had a lossy narrowing type conversion that
caused this defect, and making an entirely new codepath would've made the
interface of frame_pts (relying on things like a custom parsing routine
for the filename template "%d" specifier) incompatible with the rest of
img2enc. The new implementation should be totally backwards-compatible but
I still can't test it myself since I can't get make to work on WSL lol.
Regression tests are passed though:
